The check engine light came on the other day and my mechanic said the code was related to the fuel system and a new gas cap would solve the problem, a $7 fix. But, a few days later the code and light returned. Now my mechanic says the gasket on the gas tank needs replaced around $200. Does this sound right?

 

Tell him to give you the code it is throwing and provide that to us.

 

The EVAP leak code occurs when the fuel tank system is not airtight like it should be. Usually the leak is at the gas cap. If it's not that, a more advanced check is warranted rather than just changing parts. There is a machine that blows "smoke" into the gas filler so you can see where it is leaking out. Ask him to show you the leak.

 

I think he said it was 304 or something like that. I'll see if he can perform the smoke test. Thanks so much for the help.

 

Go to AutoZone and have them pull the CEL code. Post the exact code.

 

OK, went to autozone and had them pull up my codes. The first one is P1457, which says loose fuel cap, which it is not and I just replaced it. Also I noticed a woosh sound when I removed the gas cap today. That seems to tell me there is no leak in the system. The second code was P1298, which is connected to the ECM. This would be probably from a problem I caused. I replaced the cruise control light bulbs on the lower dash switch with led's. After replacing them I no longer had cruise control, which I had prior to replacing them. Took out the led's and cruise works again. Guess I'll have to go to Honda to get replacements. I would appreciate any help on the fuel issue.

 

Now reset the ECU to clear the codes to see whether both codes return. You don't want to chase any error codes that don't repeat.

Also check 10A fuse 4.

One cause of P1457 is a vacuum leak, but an EVAP circuit or valve problem can also throw the code.

 

how do I reset the ecu, and where is the fuse you were talking about?

 

Remove 15A hood ECU/ECM fuse #6 for a few minutes. Or use a code reader to clear the codes.

Check the lid/label on the fuse box --> 10A dash fuse #4

 

OK, I've done those two items and the check engine light is out. Thanks very, very much. Now to wait and see.
